Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional jigs or supports are used to hold chord members and web members together, then the assembly process can be performed manually, but the assembly efficiency and positioning precision are limited
Solution Approach 1:
The patent replaces manual mechanical assembly operations with automated robotic systems. Robots are used to deliver joist members to the table and perform welding operations, substituting human labor with automated mechanical systems that offer higher precision and productivity.
Solution Approach 2:
The system enables automated self-service assembly where robots autonomously handle material delivery, positioning, and welding operations without continuous human intervention. The automated system serves itself by continuously performing assembly tasks through programmed operations.
2Measurement precision
If manual delivery methods such as forklifts or conveyor belts are used, then the system is simpler, but the positioning precision and assembly efficiency are reduced
Solution Approach 1:
Traditional mechanical delivery systems like forklifts and conveyor belts are replaced with robotic material handling systems. These robotic systems provide precise positioning capabilities through automated control, enabling accurate placement of joist members at specified locations on the assembly table.
3Productivity
If more automated systems are introduced to improve assembly efficiency, then productivity increases, but the device complexity and initial investment increase
Solution Approach 1:
The automated assembly system is divided into distinct functional modules: material handling systems for delivering joist members, a rigging table system for positioning and supporting members, and welding systems for joining members. This segmentation allows each subsystem to be optimized independently while working together to achieve high overall productivity.

AI summary
A joist assembly system that is structured for dynamic retrieval of components, dynamic and precise positioning and location of retrieved components, assembly of the components to form a joist, and delivery of the assembled joist. The joist assembly system has a plurality of material handling systems, a plurality of welding systems, and a rigging table system. The material handling systems are structured to load and position the components such as chords and webs onto the rigging table. The rigging table in turn supports the chords or webs. Subsequently, the plurality of welding systems weld the webs to the chords to form the joist.
